Raytheon and the U.S. Navy completed the final developmental test to integrate the Joint Standoff Weapon C (JSOW C) onto the F-35C Joint Strike Fighter, keeping the low-cost, air-to-ground missile on track for full deployment in 2019.

The JSOW glide weapon uses a GPS-inertial navigation system with an imaging infrared seeker that can identify and track targets autonomously. JSOW C weighs 1,000 pounds and is effective against high-value land targets at ranges greater than 70 nautical miles, day or night, and in adverse weather conditions.

“With JSOW C in its internal weapons bay, the Navy’s F-35C can now eliminate the toughest ground targets from significant standoff ranges,” said Mike Jarrett, vice president of Raytheon Air Warfare Systems. “JSOW’s advanced warhead and smart fuse provide fighter pilots with plenty of flexibility against hard and soft targets — plus, it has many programmable effects.”

Lockheed Martin, manufacturer of the F-35, and the F-35 Joint Program Office participated in the latest test, which took place on the Navy’s China Lake ranges in California. The test demonstrated that the weapon could be carried inside the F-35C weapon bay and deploy seamlessly.

The weapon is already integrated with the Navy’s F/A-18 Super Hornet fighter jets and achieved operational status in June of 2016.
